Wastewater treatment, storm water drainage, and ood protection: these are classic urban development problems in Cambodia and Viet Nam.
Wastewater treatment, storm water drainage, and ood protection: these are classic urban development problems in Cambodia and Viet Nam.
Examples:
• Nature-based wastewater treatment in Cambodia
• Water-sensitive design for ood protection and water
quality improvements
• Storm water runo mitigation using absorbing surfaces
instead of traditional impermeable concrete or bitumen • Permeable drains for water to be retained, absorbed, and
transpired
• Permeable retention basins that act like sponges

“The principle is to retain the natural pre-urbanization characteristics of the watershed, which creates lower peak discharge rates. In turn, this lowers costs and reduces the capacity requirements of the infrastructure.”
